In this week's Pulse Report, the streets are buzzing about Khia firing back at Trina, Three Six Mafia invading Hollywood, Cassie's rapper report card and Jay-Z addressing sweat shop rumors.

1. Khia strikes back. Only days after being dissed by Trina on "What's Beef," Khia has fired back with "Hit Her Up." Interestingly, both femcees have borrowed from two previously feuding and unfortunately late emcees for their latest dis records. While Trina took from Biggie's "What's Beef," the Thug Misses opted to be the umpteenth rapper to recycle Tupac Shakur's "Hit Em Up." "Fake bitch if you was real you would have said my name/but I'm calling you a hoe and I'm saying it to your face/keep it real punk hoe, the hood already know/that's why they fuck you in the ass, let a hoe be a hoe/Trick should have warned you not to open your mouth/but Slip-N-Slide been begging me to fill up your spot," Khia charged. Fortunately, this one is sure to stay on wax. Khia and Trina were both at the Ozone Awards and no altercation took place.

2. Three Six Mafia takes over Hollywood. Everybody and their momma wants a piece of Three Six Mafia nowadays. Interestingly, half of them probably didn't know who the Memphis powerhouse was prior to them winning an Oscar. Tinstletown is sure to see a whole lot of DJ Paul and Juicy J in the coming months. "I ain't doing no stunt. We just playing tricks on the 'Jackass' guys. I can't tell what we doing, but we playing tricks, some funny stuff. But no, I ain't doing nothing dangerous on my part," Paul told The Village Voice's "Status Ain't Hood." The duo made an appearance on the forthcoming Jackass 2 movie and also recorded a rock a song for the flick. Also look for two Three Six songs in the upcoming Rocky flick, a cameo with Paris Hilton on "The Simple Life" and a brief appearance on HBO's "Entourage."

3. Cassie rates rappers. Cassie appeared on Hot 97 earlier this week. No, the Myspace sensation did not confirm that "Me and You" was indeed about, ummmm...brains, but during an interview with Angie Martinez, Cassie did reveal that Omarion and Bow Wow tried to holla. Later on during Funkmaster Flex's show, Cassie provided more depth into the episode, detailing that Omarion had his little brother give her his number while Bow Wow also sent his math through a third party. The beauty then rated rappers on a scale from 1 to 10. Ne-Yo, Omarion, Jay-Z, Justin Timberlake and Yung Joc all received 7s while Derek Jeter and Young Jeezy earned 5s. Juelz Santana scored a six while Bow Wow with 8 and T.I. with a 10, were the highest rated. Cassie also noted that Pharrell Williams was her top choice and was clueless as to who NBA Champion, Dwayne Wade was.

4. Jay-Z looses his cool. Jiggaman ain't likely to get pissed at anything. Dude is just too cool for school. How many cats would appear so composed while Beyonce is gyrating next to them and grabbing onto their waist, no matter what routinely happens behind the scenes. But Hov momentarily got annoyed during the conference at the UN earlier this week. The God emcee got heated when a reporter asked him whether Rocawear clothes "still were" manufactured in a Honduras sweat shop. Jigga quickly slammed his question, assuring that the brand was never made in sweat shops. The Brooklyn lyricist appeared highly aggravated when answering the following questions.
